' SPECIFICATION forming part of Letters Patent No. 662,347, dated November 20, 19O.

Application filed March 6, 1900- Serial No. 7,530. LNo modela T0 all whom it may concern.'

Be it known that we, LYMAN BROWN and HERBERT W. STURTEVANT; citizens of the United States, residing at Middleborough, in thecounty of Plymouth and State of Massaehusetts, have invented certain new and useful Improvements in Chicken-Broeders; and We do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

One object is to present a broeder which shall combine great simplicity of construction with high efficiency and durability in use and which may be operated with certainty of best results by any person of ordinary ability.

A further object is to present a broeder in which with the expenditure of a minimum amount of fuel the greatest and most constant heat may be obtained; furthermore, to present a brooder in which the incoming current of air used to support combustion shall be utilized as an additional heating means for the broeder.

With these objects in view the invention consists in the novel construction and combination of parts of a broeder, as will be hereinafter fully described and claimed.

In the accompanyingdrawings, forming a part of the specification, and in which like letters of reference indicate corresponding parts, We have illustrated a form of embodiment of our invention, it being understood that other forms of embodiment thereof may be employed without departing from the i spirit of the same.

`and its attendant mechanism. Fig. 3 isaperspective detail View exhibiting the interior arrangement of the heat-radiator. Figsand 5 are perspective detail views of the different partsof the heat-radiator. Fig. 6 is a fragmentary detail View in plan, showing the ventilating shaft exhibited in Fig. l.

To render easy an understanding of the device, the same may be described under three heads, the first relating to the broeder, with which is combined a hoverer, the second to the heat-generating chamber, and the third to the heat-radiator for heating the brooder.

The broeder comprises a casing A, which may be made of any suitable material and of any dimensions and covered by a three-part lid, whereof the center section a is preferably fixed and the two end sections a2 and a3 are hinged, so that they may be turned back when sired.

Arranged about midway of thelength of the casing is a partition a4, from which depends a curtain d5 of any suitable flexible material, which serves to divide the casing into two compartments, that under the lid ai constituting a hoverer or brooding-room and that under the lid d3 the feeding and exercising room.`

In one corner of the feeding and exercising room is an opening d, communicating with the external air, a plate a7, constituting a ventilating-shaft, being secu red to a side and end of the casing and inclosing theopening d6, serving to conduct air from the floor of the feeding and exercising room upward there-p through and out of the opening co8. The casing is also provided with suitable vents a9 to be closed by pivoted covers d10, (indicated by dotted lines in Fig. 1,) these vents to supply air to the interior of the two chambers, and with windows a, one only being shown, to render the chambers light. By the arrangement described the requisite light and ventilation will be afforded.

Secured either to a side or an end of'the casing, preferably to a side thereof, and adl.admission to the interior of the brooder is dejacent to the hoverer or broeder is the heatgenerating chamber B, the same being of any desired dimensions and provided with a door b, by which entrance to the chamber may be had. At a point near the bottom of this chamber is arranged a two-part partition, comprising a stationary portion b2 and a mov- .and when so employed the partitions will be below the shade-holder, the opening designated by bX in the center of the partition being of sufficient size to permit ready iow of air around this portion of the lamp and to the upper part of the chamber. The vpurpose of the partition is to provide a safety-compartment for the lamp-reservoir, the incoming external air passing around and over the said reservoir and serving to keep the same cool and, further, shielding the reservoir from heat-from above, and when the partitions are in place the only means of com munication of air from the lower portion of the chamber to the upper portion is through the said opening bx. Air is supplied lto the lower portion of the chamber-that is, where the lam p-body or reservoir is located-through openings b4 (shown in this instance as two in number) at each side of the chamber B, and, if desired, similar openings b5 in the door below the partition may be employed. The interior of the chamber is providedwith a lining bl, which is free from the sides, except-at a point adjacent to the partition and near the top, and the rear Wall of the chamber, which is also lined, is provided in this instance with three openings, two of which b8 constitute hot-air-escape openings and also operate to supply warm air for ventilation of the broeder in addition to their heating function, and a third opening b9, through which the lamp shade or chimney passes to the interior of vthe broeder. The lining is provided near its lowerportion on each side with a series of openings, through which the air from the combustion or hot-air chamber will pass .up between the lining and the side of the heat-generating chamber, whence it escapes through the openings bs, the lining being shown forv this purpose as dividing the openings, so that one half of each of the openings b8 will cornmunicate with the heat-generating chamber and the other half with the space between the top of the lining and the top of the said chamber.

The lamp shade or chimney, as stated, projects inward to the broeder and is curved upward and enters an opening or mouthpiece provided on the under side of the heateradiator C, which will now be described. Each section of the heat-radiator consists, practically, of a shallow pan titted one within the other, and secured inL any suitable manner between these pans is a strip of metal c2, formed into a spiral, constitutinga duct to cause the heated products ofcombustion from the lamp to traverse from the entering-point c8 tothe center of the brooder, whence it escapes through an opening or pipe c4', provided for the pur-- pose. `The heat-radiator lis1 secured to the under side of the lid a2 inany manner, as by platesc5 and screws c6, although it is to be understood that they may be secured in place in anyother manner, andthe lamp-chimney enters the mouthpiece c7, which is provided at the opening c3, so that there will be no escape into the broeder of incomplete products `of y combustion yfrom the lamp. By the arrangement shown it will beseen that the radiator may be turned back out of the way-of the lamp, so that accessto the broeder may be had without in any manner disturbing any of its parts, and should it be desired to cleanse the interior of the radiator it will only be necessary to loosen thevscrezws c6 and -detach the platesc5. Arranged between the heat-radiator and the lid a2 isa convex heat-relector cs, the convex side whereof is arranged Vdownward, so that the heat that radiatesfrom the top 4of the radiator will lbe thrown downward and distributed intothe chamber.

Having thus described our invention, what we claim as new, and desi-re to secureby Letters Patent of the United States, vis

1. The combi-nation with a broeder `having a movable cover, of a heat-radiator secured thereto, a spiral iue within the radiaterand heating means in communicationfwith the heat-radiator, substantially as described.

2. The combination with a broeder having a movable cover, of a heat-radiator secured thereto, a-delecting-plate, between the radiator and the cover, and heating means incommunication with the heat-radiator, substantially as described.

3. The combin-ation with a brooder, of an exte riorly-arranged heating-chamber divided by a horizontal partition into two compa-rtments, the lower compartment communicating with the outside air, a lamp-or other like heating means having its reservoir arranged below the partition, and a chimney extending into the brooder, an air-escape space formed in the partition whereby the air taken into the lower portion of the chamber may be fed to the upper portion thereof to support combustion, incombination with a heat-radiator carried by the cover of the broeder and with tially as described.
